Hi Yonik, Thanks for your reply.
All our hits are coming from SAP HYBRIS SERVER (hosted on tomcat). However, what I am still not sure if what process will initiate these requests. We are not using any hardware load balancer between hybris and SOLR. So may be LBHttpSolrClient is the one making these hits. But the question is under what scenario will these hits be made and why will it always result in 404. Is there a way to figure out where exactly these hits must be getting triggered from? On hybris back end servers only indexing jobs run which queries DB, creates document and push to SOLR. These jobs are scheduled to run in every 3 minutes. However, the queries which we are seeing are actually getting triggered in seconds. So still puzzled to know what process is triggering it and how can we supress it. Also why these queries are getting triggered on other environments except production. Also can you let me know why would this ping type of hits will lead to memory consumption??
